UNITED STATES I PATENT GFEICE.

PATRICK J. KELLEY, OF ST. LOUIS, MISSOURI, ASSIGNOR TO THE \VHITMAN AGRICULTURAL COMPANY, OF SAME PLACE.

CONTINUOUS :BALlNG-PRESS.

v SPECIFICATION forming part of Letters Patent No. 282,089,. dated July 31, 1883.

Application filed June 13,1883. lNo model.)

To all whom, it may concern:

Be it known that I, PATRICK J. KELLEY, a citizen of the United States, residing at St.

Louis, State of Missouri, have invented certain new and useful Improvements in Continuous Baling-Presses, of which the following is a specification, reference being had therein to the accompanying drawings.

.My invention relates to improvements in the continuous or perpetual baling press patented to Gustavus F. Vhitman, March 27, 1883, No. 274,871; and it consists of certain changes in the construction of some of the parts, which will herein after be fully described and specifically claimed.

In the drawings, Figure l is a top plan view of the press referred to with my improvements applied thereto. Fig. 2 is a side elevation of the front of the press with a portion broken away. Fig. 3 is a detailed perspective view of a portion of the door and its spring-catches. Fig. 4 is a perspective view of the brackets and levers for operating the door. Fig. 5 is a broken perspective view of the tripper attached to the top portion of the traverser.

The general construction of the press is the same as in the patent above referred to.

A is the press-box, which is preferably mounted on wheels, so as to be portable; but my improvements are equallyapplicable to stationary presses.

B is the traverser, C the toggle arm or lever, and D the sweep; but as all of these parts are similar to like parts in the patent referred to, and mounted on the frame or box in substantially the same manner, they need not be specifically described, as they form no part of my present invention. .The same is true of the automatic retainers which are used to prevent the material which is to be baled from following the retrograde movement of the traverser.

My improvements relate to novel means for automatically opening the door of the press. The door F is hinged or pivoted to the top portion of the frame-work, as at E E, by means of segmental hinges or points 0 e, which are made with round pintles at their ends, and flattened segmental extensions, which are nearly the width of the door and secured to the 50 top thereof. By making these points i of this form I am enabled to bring both of the pintles 011 the same transverse line, and the segmental extensions which extend across the dooradd greatly to its strength and prevent its splitting. 'At the other end of the door, and on the 5 5 top thereof, I secure a flange-plate, G, carrying the mechanism for locking the door in a closed position, as plainly shown in Fig. 3. This plate carries two spring-bolts, g g, which engage with suitable catches, h h, in a cross beam or bar, H, on the top of 'the press-box.

The plate G has an upwardly-projecting flange, g, throughwhich the bolts g 9 pass, and is also provided with two angle-pieces,

g g, the upper arms of which lie upon the top of the beam II when the door is closed. The two bolts are connected at their front ends by a cross-bar, f, and at or near the center of this crossbar I attach a suitable cord or chain,

f, for operating the bolts. under a sheave or pulley, f, secured to the door'in front of the bolts, and the other end of the cord or chain is secured to a pivoted upright lever, as will be hereinafter explained.

It is evident that more than two bolts may be used, if desired, and in some instances one broad flat bolt might be sufficient; but I prefer the construction just described.

In front of the point at which the door is hinged or pivoted, and to the beam N on top of the press-frame, I secure two substantially triangular brackets, J J. (See Fig. 4.) These brackets are provided with lugs j j, the front ones of each bracket embracing the corner of the beam or brace N, and the rear ones secured or bolted to a brace, O, immediately in front of the door. The brackets are thus held in a vertical position, and are provided with suitable transverse stays or bolts. An upright lever, with holes in its top or long- 0 est arm, in which the cord or chain f is scoured, is pivoted between these brackets by means of the holes 0 O and a rod or pintle at the top, and the bell-crank lever K, Fig. 4, is pivoted in like manner at the lower front 5 ends of the brackets. One arm of this lever K extends upwardly andrests against the lower rounded end of the short arm of the lever 'I, while the other end extends downwardly, and is limitedin its movement toward This cordis passed 70 the door by meansof the stud or pin K. Stops or arms j j are also attached to the top of the brackets to prevent the door from being thrown .too far open.

011 the top of the top portion of the sliding frame to which the traverser is attached, between suitable lugs, I provide a weighted pawl or tripper, L, as plainly shown in Fig. 5. A

,weighted lever, M, is attached to one or both IO sides of the door, either by extending one of the pintles for the purpose, or such levers may be attached in any other known manner.

The operation of my invention is as follows: In Fig. 1 the traverser is shown in its most-ad vanced position, and the toggle-lever and the mechanism which connects it with the sweep are in a straight line but when power is ap plied to bring the sweep around, the traverser begins its retrograde movement, and when the 20 tripper L reaches the lower end of the bellcrank lever K it trips it. The upper arm of this leveris thus pressed against the short arm of the upright lever I, throwing its long arm forward, thus drawing on the cord and releasing the spring bolts or catches. As soon as the bolts are released the door is thrown open against the stops on the brackets by means of the long-armed lever and weighted lever, and a charge of the material to be baled is then fed into the pressnrc-chamber. The door is then closed by hand, the catches or bolts engaging automatically and holding the door shut while the material is being pressed and until the traverser begins its retrograde movement.

The pawl or tripper L is so constructed that while it trips the bell-crank lever during the backward movement of the traverser it does not touch it in its forward movement.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a continuous baling-press, a door provided with suitable locking-bolts, which are adapted to be released by means of a cord or chain, an upright lever, and a bell-crank lever pivoted to brackets on the top of the press, said lever being actuated by a tripper on the traverscr when the sweep is operated, sub stantially as set forth.

2. A continuous baling-press having a door provided with locking-b olts, which are adapted to be automatically released by the operation of the traverser and sweep, in combination with a weighted lever or levers for throwing the door open, substantially as set forth.

3. In a continuous baling-press, the traversor provided with a tripper or weighted pawl, L, adapted to operate a series ofpivoted levers, and acord or chain for releasing the lockingbolts 011 the door as the traverser is moved forward, substantially as set forth.

4. The combination, in a continuous balingpress, of brackets attached to the top of the frame, and stops secured to said brackets, to prevent the door from being thrown too far open, substantially as described.

5. In a continuous baling-press,a door pivoted by means of segmental hinges extending across the same, and having their pintles tended and carrying the weighted levers for throwing the door open, as set forth.
